v This invention relates to the manufacture ofmetal' cans and'containers andhas special reference to the removal of excess solder and the formation of a smooth surface along the soldered seams of the cans and containers during their formation.

The invention'pertains to an apparatus or machine for manufacturing metal containers in which it is required seams of a series of containers as they are thevarious seams to be solderec 'b'ein successively passed through solder baths. der has been madethe ca'n's orcon tainers are to the action of a' new and improved mechanism orappa'r'atu's' by which the excess solder is removed and an even surface is made over the soldered seam.

According to my-invention I apply suitable buffs .or wipers rotating in different planes across the soldered seam in order. to

simple and improved mechanism which is so constructed and arranged that the entire drlv'en b y suitable means. (not shown) and width of several buffs comes'i'n contact with the edge of the can,

While a single solder wiping machine is shown for purposes of'il'lnstration it is to be understood that a number of machines may be used together and a single track provided for carying the canspast the wipersor buffs of the several will betu'rne d to exposepdiflerent edges or seams to the action of the buffs of the different machines.

framework 10 and mounted thereon is a gear wheel 16 which carries. one end of a link chain 17. The opposite end of the chain 17 is carried on a gearwheel18 mounted on a machines. In 3 such event the track is V V 'c'ammed at regular intervalsso that the cans A driving shaft 15 isjou'rnaled in the shaft 19 "ofa motor 20, the motor being A plurality of substantially vertically disposed rotatable shafts 21 are geared at one end to the driving shaft 15 'as at 22, each of formed integral withspaced housings 2 1 on providing the motive force'for operating the dr1ving'shaft15'.

By thusenclo'si'ngthe gears in the housings 24L th'eunatterof hibri'cating them'is simplified'a's, thelubricant can readily be placed r directly in the housings.- Each bracket 23 is thus in effectxpivoted'u'pon the driving shaft 15 and each sis-formed with Adjusting screws 26 which work in nuts 27 are provided fonadjusting the shafts 21.

The screws 26 are provided with suitable mounted in the frame of the machine.

thereby form an acuteangle with respect to the edge of the cans with which they are adapted to contact. As illustrated, a block 29 is formed integral with each of the upper bearing blocks and the block 29 is screwconnected to the nut 27. Thus the position of the shafts 21 can be readily varied without in any way interfering with the operation of the machine.

In addition to the buffs 28 mounted on the shafts 21 there is provided at least one other buff, such as 30, which is positioned in a plane at substantially right angles to the edge of the can to be wiped. The buff 30 is mounted on a shaft 31 which is suitably journalled in a bracket or block mounted in the frame of the machine.

The shaft 31 is provided with a gear wheel which carries alink chain 34, the opposite end of which carried. by a gear wheel mounted on the main driving shaft 15. Thus it will be seen that the shafts 21 and 31 are all driven by the common driving shaft 15.

The bracket or block 32 mounted in the frame of the machine .in such a way as to provide for a necessary amount of longitudinal movement. An adjusting screw works in the bracket or block 32 and on one end of the screw there is mounted a bevel gear 34 which meshes with another bevel gear 35 positioned on a shaft 36 which is One end of the shaft 36 is provided with a hand wheel 37 so that by occasionally turning the handwheel the buff 30 on the shaft 31 may, although wearing away with use, be kept in wiping contact with the edges of the cans. The entire machine is preferably on closed within housing 89, provision of course being made in the top to allow for the contact between the bulls and the cans.

The operation ofas follows:

The motor 20 is first started, thereby putting the driving shaft 15 into operation, as well as the shafts 21. and 31 upon which the buffs 28 and 30 are mounted. At the same time the conveyor 13 is started so that while the several buffs are rotating a succession of cans advanced along the track ll and an edge of each can, after the necessary solder has been applied, comes in wiping contact with. the several buffs so that all excess solder is removed and a smooth the apparatus is briefly seam formed.

As has already been stated, the bull's 28 are arranged as such an angle with respect to the exposed edges of the cans that the entire width of each buff comes in wiping contact with the edges of the cans. The rr-zlative positions of the buffs 28 and'the edges of the cans being wiped are such that the ed e of each can makes an acute-angle "'h each buff 28. An angle of approxi- 1 15 has, in practice, been found to be quite satisfactory. The buff 80, as has already been explained, is positioned at right angles with respect to the edge of the can to be wiped. Thus in passing. along the track 11 an edge of each can is subjected to the action of a number of buffs arranged at an acute angle and of at least one buff arranged at right angles with respect to the edge of the can. The combined action of the buffs effects an extremely neat soldered seam.

Apparatus of preferred form and construction has been shown and described for the purpose of showing one way in which this invention may be practiced, but the invcntive thought upon which this application is based is broader than this illustrative embodiment thereof. It is, therefore, understood that the scope of the invention is not to be limited by the present disclosure, reference being had to the appended claims for that purpose.

What I claim is:

1. In a solder-wiping machine, the combination with means for moving a plurality of spaced cans with a seam of each can exposed, of a plurality of rotatable buffs adapted to successively engage the exposed seams of said cans, a portion of said buffs being disposed at an acute angle with respect to said exposed seams so that the entire width of each of said buffs comes in contact with the edge of the can and another bufl' disposed in a plane at right angles thereto.

2. In a solder wiping machine, the combination with means for moving a square can. with an end seam of the can exposed, of a rotatable bufl' disposed at an acute angle with respect to the exposed edge of the can and adapted for wiping engagement there ith, and a rotatable buff disposed at substantially a right angle with respect to said edge and adapted. for wiping engagement therewith.

In witness whereof I have hereunto set
